Special Issue Information

Dear Colleagues,

Innate immune cells, including macrophages, neutrophils, dendritic cells (DCs), and innate lymphoid cells (ILCs), are the first line of defense against cancer development and infections. These cells respond to initial perturbations in the tissue, which can result in either control or even prevention of tumor initiation and progression. But, as tumors develop immune evasive mechanisms, innate immune cells can also facilitate tumor progression and metastasis. The overall outcome of the innate immunosurveillance is determined in the specific context of the tumor microenvironment and differs by the tumor type. Therefore, understanding the influence and mechanisms underlying both pro- and anti-tumor effects of the innate immune system is crucial in fighting cancer.

This Special Issue will collect a series of reviews and original articles describing basic science, preclinical, and clinical investigations, covering all aspects of innate immune surveillance from tumor initiation, progression, and metastasis. Potential topics include but are not limited to tumor immune microenvironments with emphasis on innate immune cells, innate immune receptors and signaling, molecular mechanisms of innate immune evasion, engineering innate immune cells, novel immunotherapies, and mechanisms of resistance to immunotherapies.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Cancers is an international peer-reviewed open access semimonthly journal published by MDPI.

Colorectal cancer (CRC) is a leading cause of cancer-related deaths worldwide, and innate immune responses and inflammation are known to affect the course of disease. Interferon (IFN) signaling in particular is critical for modulating inflammation-associated diseases including CRC. While the effects of IFN signaling in CRC have been studied, results have been conflicting. Furthermore, individual molecules in the IFN pathway that could be therapeutically targeted have distinct functions, with many of their diverse roles in CRC remaining unclear. Here, we found that IRF9 had an oncogenic effect in CRC; loss of IRF9 reduced tumorigenesis in both azoxymethane (AOM)/dextran sodium sulfate (DSS)-induced and spontaneous CRC models. IRF9 also reduced DSS-induced colitis and inflammation in the colon, but it had no effect on the NF-κB and MAPK signaling activation. Instead, IRF9 enhanced the transcription and production of the inflammatory cytokine IL-6. By promoting IL-6 release, IRF9 drove the activation of pro-oncogenic STAT3 signaling in the colon. Overall, our study found that IRF9 promoted the development of CRC via modulation of the IL-6/STAT3 signaling axis, identifying multiple potential targets and suggesting new therapeutic strategies for the treatment of CRC.
